Abstract: The invention relates to a system and apparatus for use with a vehicle having a dump bed for carrying a material and having a moveable panel defining an outlet in the dump bed for dispensing material carried in the dump bed to a road surface when the dump bed is raised, comprising a baffle positioned in the dump bed extending upwardly from a floor of the bed, and extending from a region of the moveable panel to a region of a wall of the bed for directing the material to a portion of the outlet as gravitational force acts on the material when the dump bed is raised. Such system and apparatus may further include a receptacle coupled to the vehicle for receiving a flow of the material passing through the portion of the outlet and having a variable opening for dispensing controlled amounts of the material to the surface. Such system and apparatus may further include a leveling sled for leveling the material after the material leaving the dump bed reaches the road surface.

Abstract: An apparatus including a rigid shaft and terminating at a lower pointed end, with a mounting head integrally formed and aligned with an upper terminal end of the shaft. The mounting head includes a plurality of spaced parallel plates formed with apertures therethrough to receive fasteners to be directed within a post mounted within the head. The shaft includes a helical web integrally mounted to the shaft adjacent the lower terminal end, and optionally includes a second helical web mounted to the shaft spaced between the mounting head and the first helical web to direct soil upwardly of the shaft interiorly of a ground support surface.
